Sweet. I really like the rusty color scheme going on, especially in the second shot.

In the third shot, I'd maybe replace the vertically-tiled brown metal rivet trim on the floor with something else, as it's currently repeating three times in a row between the trim and the railing immediately above it.

Cool pics!
Looks a little hellish for an early map, but one thing I like about community projects is the thematic inconsistency (which only works well in community projects).
In the second shot, the floor flats used look a little strange next to each other. Maybe add borders?

Wow, those screenshots look pretty cool! the second shot actually gives the feel as if your in an old castle from the medieval age. the third pic makes it feel as if you're out of the castle, but not being in the open. really love the effects. I only have two words for this map: Darkish Epic!

Thanks for the comments guys, I'm still certain the map only needs a few months of work, it's just a matter of sitting down and getting it done.

That flat is actually the top of a wall that has lowered.

I see what you mean, but I like the way the rivets continue from the adjacent wooden texture. Maybe I can find/make a better bars texture without rivets. Oh dear, look at the time...
